Mechanical stapling is a major treatment in digestive tract reconstruction surgery. Although this technology has been proved effective, problems such as anastomotic leakage still exist [1]. Because complications can arise from generally subjective judgments made by surgeons on aspects such as the choice of staples and pressing intensity of the stapler [2], medicine would improve if staplers were more intelligent.
Understanding the structural changes of tissue under compression is the basis for developing intelligent stapling technology. Staple-line blood flow was measured through laser Doppler velocimetry in colonic anastomoses [3], and the output of intracellular fluid was measured using a potassium solution [4]. To date, there has been little research on how tissue structures change under stapler compression.
The ColeY model has been widely used to analyze body-water components and to study the internal structural changes that...
